SPECIFICATION forming part of Letters Patent No. 368,798, dated August 23, 1887.

Application filed February 5, 1887. Serial No. 226,706.

To all whomit may concern:

Be itknown that I, ELIJAH WARE, of Omaha, in the county of Douglas and State of Nebraska, have invented a new and Improved Injector, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved injector, in which the proportion of steam and water is governed at the point of contact.

The injector is also simple in construction and very effective in operation.

The invention consists in the construction and arrangement of parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improvement. Fig. 2 is a sectional plan view of the same on the line now of Fig. 1. Fig. 3 is a side elevation of the regulating-cone. Fig. 4. is a side elevation of the check-valve. Fig. 5 is a longitudinal central section of my improvement. Fig. 6 is an end elevation of the steam-inlet casing. Fig. 7 is a sectional side elevation of the overflow-valve in a closed. po-.

sition. Fig. 8 is a plan view of the steamvalve, and Fig. 9 is a plan view of the steamvalve seat.

My improved injector is provided with the casings A'and B, secured together at right angles by bolts or other means. The casing A is provided with the steam-inlet pipe A, and with an offset, A on which is held the valve-seat 0, consisting of a disk, 0, (see Fig. 9,) having the ports 0, G", and 0*, and of a hollow reduced stem, G which supports the seat-disk O and passes to the outside of the casing A, being firmly secured thereto by the nut G", screwing on the threaded end of the said stem 0 and against the bottom of the casing A.

The valve D is provided with a disk, D, operating on top of the seatdisk G and having the ports D and D adapted to connect with the ports 0, C and C of the seat-disk O. The valve-disk D is supported on a stem, D passing through the hollow stem 0", and provided on the outer end with a lever, E, by which the said valve D can be turned so that (ModelJ its ports D and D are connected with or disconnected from the ports in the seat-disk O.

The port 0 of the disk 0 continues down ward in an offset on the stem (3 and. opens into the ejecting or starting cone F, secured to the casing A and projecting centrally into the casing B at right angles to the casing A. The other ports, 0 and 0 open into the space A surrounding the stem 0 and the said space A connects by the apertures A with the interior of the regulating-cone G, held loosely on the bearing A, formed in the casing A and projecting centrally into the casing B.

The cone G can be moved forward and backward in its bearings A by a screw-rod, G, which projects to the outside, or by other suitable means. The rcgulatingcone G is concentric with the ejecting or starting cone F, and opens upon the rim of the latter. The casing B is provided with the downwardlyextending water-inlet pipe H, in which; is pivoted the water-regulating valve H, which has one of its trnnnions, H, projecting to the out- .H and the casing A, and in line with the cones F and G. The outer end of the pipe B is secured to the boiler or other apparatus to be provided with my injector. In the pipe B is held the main double cone J, of which the front cone,J, isacombinatiouconeflnto which open the ejecting-cone F and the regulatingcone G. The front end of the cone J is held in a nut, K, secured to the delivery-pipe K, having in its front the usual check-valve, L, held in the end of the pipe B. The other part, J of the cone J is the waterinlet cone, which surrounds the regulatingcone G and opens at its large end into the casing B, and is thus connected with thewater-inlet pipe H.

The overflow-pipe N enters the bottom of the pipe B between the bearing of the double cone J and the nut K, and is provided with a valve, 0, having the stem 0, on which is secured a crank-arm, P, connected with the crank-arm I by the link P. This arrangement permits of operating the overflow-valve O, the water-valve H, and the steam-valve D .portsG and G also provided with a right-angular aperture,O",

of which the upper arm is connected with or disconnected from a channel, Q, formed in the casing B, and connecting with a channel, R,

formed in the casing A. The channel R connects with the lower end of the port 0' in the seat 0. The other lower arm of the aperture 0 opens downward into the pipe N. I

The operation is as follows: The injector is set in operation by first starting the ejector F, which is done by moving the lever E in, the direction of the arrow a, (see Fig. 2,) so that the port D in the valve D comes over the port 0 in the seat 0, thus admitting steam to the ejecting-cone F. The movement of the lever E also opens the water-valve H, and water is forced into the cone J by the action of the steam in the ejector F. Partof the steam entering the port 0* passes into the channels R and Q and into the right-angular aperture 0 of the valve 0, and thereby creates a downward suction in the overflow-pipe N, so that the water accumulating in front of the combination-cone J flows from the pipe K through the nut K and out of the pipe N through the central aperture, 0', in the valve 0. Theoverfiow-valve O commences to close as soon as the valve E opens, with its ports D and D upon the ports 0 and O" of the valveseat 0, and when the operator sees that water flows out of the overflow-pipe N then he moves the lever E still farther and opens the valve D fully, so that the ports D and D are over the ports 0, G and 0*, and steam now enters the regulating-cone G and then passes into the combination-cone J. The starting or ejecting cone F remains open, as the port D is sufficiently large to open into both (See Figs. 8 and 9.) When the valve is entirely open, the overflow-valve is closed, as shown in Fig. 7-that is, the central aperture, 0', is disconnected from the up per and lower ends of the pipe N, and the angular aperture 0 is disconnected from the channel Q and the lower end of the pipe N.

If sufficient steam does not enter the combination-cone J, then the regulating-cone G is moved forward by its screw-rod G, so as to enlarge the space between the regulatingcone G and the ejecting-cone F, and to diminish the space between the outside of the regulating-cone G and the rear water-cone,J,of the double cone J, whereby a greater amount of steam is permitted to enter the combinationcone,while the water-supplyis lessened. By this means I am enabled to regulate with great precision the supply of steam and water by one and the same movement simultaneously.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

' 1. In an injector, the combination, with the steam-inlet valve and the water-inlet valve, of means, as described, for operating the said valves simultaneously, substantially as shown and described. 7

2. In an injector, the combination, with the ejecting-cone and the main or combination cone, of a steam-inlet valve, a water-valve, and means, as described, for operating the said valves simultaneously, substantially as specified.

3. In an injector, the combination, with the ejecting-cone, the main or combination cone, and the overflow-pipe, of a steam-inlet valve, a water-valve, an overflow-valve, and means, as described, for operating the three valves simultaneously, as set forth.

4. In an injector, the combination, with the steam-inlet valve, the water-valve, and means,

as described, for operating the said valves simultaneously, ofa regulating-cone and the main or combination cone, substantially as shown and described.

5. In an injector, the combination, with a steam-inlet valve, the water-valve,and means, as described, for operating the said'valves simultaneously, of an ejecting-cone, a regulating-cone, and a main or combination cone, substantially as shown and described.

6. In an injector, the ejecting-cone, the main or combination cone, andthe overflow-pipe,

.in combination with a steam-inlet valve, a

water-valve, an overflow-valve adapted to be connected with the inlet-port of the steamvalve, so as to cause a suction in the said overflow-pipe, and means, as described, for operating the three valves simultaneously, substantially as set forth. ELIJ AH WVARE.
